Abstract

PURPOSE:To arrange and accumulate a fishing net on the deck of a fishing ship by a few operators by disposing a fishing net-lifting guide roller rotated with a driving device toward the stern or stem of a fishing ship in a freely movable state and widening and guiding the fishing roller with the fishing net-lifting guide roller, the fishing net being sagged from a net-handling roller disposed in a state freely movable toward the stem of the ship. CONSTITUTION:The front ends of booms 2 and 11 are connected to two masts 3, respectively, disposed on both the sides of the fishing ship 1 in a standing state. Fishing net-lifting guide rollers 10 and 18 rotated with driving devices are attached to the respective other ends of the booms 2 and 11 in a state freely movable toward the stern or stem of the ship. when the fishing net 23 is lifted from sea, the fishing net 23 sagged from a net-handling roller 9 disposed in a state freely movable toward the stern or stem of the ship is widened and guided with the net-lifting guide rollers 10 and 18. As the lifting of the net is proceeded, the net-handling roller 9 is transferred to the of the stem of the ship and the net-lifting guide rollers 10 and 18 are also transferred to the side of the stem to arrange and accumulate the fishing net 23 on the deck of the ship.

The side part of the fishing net 2 hanging down from the net handling roller 9 can be always guided toward the deck on the side of the fishing boat 1 by the net guide row.
3 can be easily arranged and deposited on the deck of the fishing boat 1 by a small number of workers.

Further, according to the second invention, the fishing net on the sinker side of the fishing net 23 hanging down from the net handling roller 9 provided above the intermediate portion in the width direction of the fishing boat 1 is rotated by the net lifting device 8. The fish net on the float side of the fishing net 23 that is guided by the sinker side lifting net guide roller 10 and guided onto the deck on one side of the fishing boat 1 and hanging down from the net handling roller 9 is used for lifting net. Driving device] While being guided by a float-side lifting net guide roller 18 rotated by a float-side net guide roller 18, the net is guided onto the deck on the other side of the fishing boat 1, and as the net moves forward, the net handling roller 9 is moved to the stern side. Even if the movable net guide rollers 10 and 18 are moved toward the stern side by moving each movable support unit 64, 65 by each moving drive device 4-13, Therefore, the net 23 hanging down from the net handling roller 9 can be always spread and guided by the sinker side lifting net guide roller 10 and the float side lifting net guide roller 18. 9
The fishing nets hanging down from the fishing net 23 (fish nets on the sink side and fish nets on the float side) can be easily aligned and deposited on the deck of the fishing boat 1 by a small number of workers.
